Command blocks only teleporting one team when using @a[team=!<teamName>]

I was in multi-player and I had a launching system where everyone not on a specific team had to be teleported but it only teleported the team with the player closest this doesn't seem like the correct behaviour as you would expect it to teleport all the players not on that team. It also did this with other comamnds such as /effect and /gamemode

I searched but I could not find something similar.
